Yes, there is a point in having 12GiB RAM on the card: There are people who can make use of it, even with existing applications. It's also a good way of driving development. This also ties in with your cluelessness about Compute performance: while DP is low, not all Compute tasks need DP. Signal processing for example is a field where DP is a waste. Take music for example. Softsynths that do physical modelling require a lot of resources, both in terms of processing and RAM, but you only need single precision(Until the end, when it's converted over to integer). Now, with this Titan card, you have massive SP compute performance, AND lots of RAM to work within.
There's also real-time simulations, where this card with all that RAM and the Universal Physics Solver will enable to run high frame-rate sims at decent resolutions and decent detail, with a good approximization of the physics involved, which is useful during design phases for example. And since it's a single GPU, development becomes easier.
